➤ Novel (i.e., quantitative and semiquantitative) cartilage imaging techniques can evaluate cartilage composition to augment information obtained from traditional magnetic resonance imaging sequences that detail morphology.
➤ A well-defined role for drugs leading to chondroprotection has not yet been determined.
➤ Shortcomings of bone marrow stimulation include limited production of hyaline repair tissue, unpredictable repair cartilage volume, and a negative impact on later cellular transplantation if required.
➤ The role of biological augments, such as cellular concentrates or platelet-rich plasma, remains undefined. When their use is reported in the literature, it is important that their process of production and characterization be detailed.
➤ Rehabilitation programs, incorporating controlled exercise and progressive partial weight-bearing, are an important part of cartilage repair surgery and should be detailed in reports on operative techniques applied.
➤ Malalignment, meniscal injury, and ligament deficiency should be corrected in a staged or concomitant fashion to reduce the overall likelihood of mechanical failure in cartilage repair surgery.
